One of the few ways to measure the properties of dark energy is to extend the Hubble diagram (HD) to higher redshifts with gamma-ray bursts (GRBs). GRBs have at least five properties (their spectral lag, variability, spectral peak photon energy, time of the jet break, and the minimum rise time) that have correlations to the luminosity of varying quality. In this paper I construct a GRB HD with 69 GRBs over a redshift range from 0.17 to >6, with half the bursts having a redshift larger than 1.7… Expand

Gamma-ray bursts (GRBs), as a possible probe to extend the Hubble diagram to high redshifts, have attracted much attention recently. In this paper, we select two samples of GRBs that have a plateauExpand
An updated Gamma Ray Bursts Hubble diagram
Gamma-ray bursts (GRBs) have recently attracted much attention as a possible way to extend the Hubble diagram (HD) to very high redshift. To this aim, the luminosity (or isotropic-emitted energy) ofExpand
Are There Any Redshift > 8 Gamma-Ray Bursts in the BATSE Catalog?
Several luminosity indicators have been found for gamma-ray bursts (GRBs) wherein measurable light-curve and spectral properties are well correlated with the peak luminosity. Several papers have eachExpand
Constraints on w0 and wa of dark energy from high-redshift gamma-ray bursts
We extend the Hubble diagram up to z= 5.6 using 63 gamma-ray bursts (GRBs) via peak energy–peak luminosity relation (so-called Yonetoku relation), and obtain constraints on cosmological parametersExpand
A cosmology-independent calibration of gamma-ray burst luminosity relations and the Hubble diagram
An important concern in the application of gamma-ray bursts (GRBs) to cosmology is that the calibration of GRB luminosity/energy relations depends on the cosmological model, due to the lack of aExpand
Slope evolution of GRB correlations and cosmology
Gamma -ray bursts (GRBs) observed up to redshifts z > 9.4 can be used as possible probes to test cosmological models. Here we show how changes of the slope of the luminosity L � -break time T � aExpand
Confronting the Hubble diagram of gamma-ray bursts with Cardassian cosmology
We construct the Hubble diagram of gamma-ray bursts (GRBs) with redshifts reaching up to z~6, by using five luminosity versus luminosity indicator relations calibrated with the Cardassian cosmology.Expand
Are long gamma-ray bursts standard candles?
Gamma-ray bursts (GRBs) are widely proposed as an effective probe to trace the Hubble diagram of the Universe in high-redshift range. However, the calibration of GRBs is not as easy as that ofExpand
High Redshift Gamma-Ray Bursts as a Probe of the Early Universe and First Stars
Gamma-ray bursts (GRBs) are the most violent explosions in the universe. Thanks totheir extreme brightness, GRBs can be detected up to the edge of the visible universe.As bright beacons in the deepExpand
Measuring the Universe with Gamma-Ray Bursts: status, perspectives and SKA contribution
Despite they are not standard candles, the investigation of Gamma–Ray Bursts (GRBs) as a tool for measuring the geometry and expansion rate of the Universe is strongly motivated by their uniqueExpand


Gamma-Ray Burst Hubble Diagram to z = 4.5
Gamma-ray bursts (GRBs) are tremendous explosions visible across most of the universe, certainly out to redshifts of z = 4.5 and likely out to z ~ 10. Recently, GRBs have been found to have a roughlyExpand
A Mean Redshift of 2.8 for Swift gamma - ray bursts
The high mean redshift of GRBs and their wide redshift range clearly demonstrates their suitability as efficient probes of galaxies and the intergalactic medium over a significant fraction of the history of the Universe. Expand
GRB 050904 at redshift 6.3: observations of the oldest cosmic explosion after the Big Bang
Optical and near-infrared observations of the afterglow of the gamma-ray burst GRB 050904 show that the detection is consistent with the expected number of GRBs at z > 6 and shows that GRBs are a powerful tool to study the star formation history up to very high redshift. Expand
Spectroscopy of the Host Galaxy of the Gamma-Ray Burst 980703
We present spectroscopic observations of the host galaxy of the -ray burst (GRB) 980703. Several emission and absorption features are detected, making the redshift, z = 0.966, completely unambiguous.Expand
Redshifts and Luminosities for 112 Gamma-Ray Bursts
Two different luminosity indicators have recently been proposed for gamma-ray bursts that use gamma-ray observations alone. They relate the burst luminosity (L) with the time lag between peaks inExpand
Gamma-Ray Burst Energetics and the Gamma-Ray Burst Hubble Diagram: Promises and Limitations
We present a complete sample of 29 gamma-ray bursts (GRBs) for which it has been possible to determine temporal breaks (or limits) from their afterglow light curves. We interpret these breaks withinExpand
Gravitational lensing effects on the gamma-ray burst Hubble diagram
Gamma-ray bursts (GRBs) offer a potential way to extend the Hubble diagram to very high redshifts and to constrain the nature of dark energy in a way complementary to distant type Ia supernovae.Expand
On the spectral energy dependence of gamma-ray burst variability
The variable activity of a gamma-ray burst (GRB) source is thought to be correlated with its absolute peak luminosity—a relation that, if confirmed, can be used to derive an independent estimate ofExpand
An apparently normal γ-ray burst with an unusually low luminosity
Much of the progress in understanding γ-ray bursts (GRBs) has come from studies of distant events (redshift z ≈ 1). In the brightest GRBs, the γ-rays are so highly collimated that the events can beExpand
